Relationship between cardiorespiratory fitness and executive function in adolescents
Objective To explore the relationship between cardiorespiratory fitness and executive function in Chinese adoles-cents,so as to provide a reference for promoting the overall development of Chinese adolescents'physical and mental health.Meth-ods From September to December 2022,a total of 5 018 adolescents aged 13 to 18 years from Shanghai,Suzhou,Taiyuan,Wuyuan,Xingyi,and Urumqi were selected by stratified cluster sampling method to assess cardiorespiratory fitness and executive function.Pearson's correlation and linear hierarchical regression were performed to analyze the relationship between cardiorespiratory fitness and executive functions.Results Among the sample of adolescents,maximal oxygen consumption(VO2max)was negatively correlated with the refreshing(1-back,2-back)and conversion executive function responses(r=-0.07,-0.12,-0.12,P＜0.01).Linear regression analysis showed that VO2max was negatively correlated with the reaction times of the refreshing(1-back,2-back)and conversion functions(B=-2.99,-6.44,-1.69,P＜0.01).Conclusions Higher cardiorespiratory fitness among adolescents is associated with better performance in executive function.Teenagers should strengthen high-intensity cardiopulmonary endurance exercise to promote the improvement of executive function.
